Summer students at CERN lives in CERN Meyrin hostel nowadays. I heard that this make life much easier for them. But it is more affordable than anything in Geneva or Meyrin. And definitely would fit the low O(2) accepted students. At the expense of "gently" kicking everyone else.

Hopefully the students weren’t low O_2 when they lived in bunkers.

I realized now that I used this jargon and would have different meaning too :D

Just for reference, some people in particle physics would use this to refer to O(x) where x is the order of magnitude number. so O(2) would means hundreds. So “low O(2)” would mean low hundreds, say around 200–300.
